Dinoflagellates: Fossil motile-stage tests from the Upper Cretaceous of the northern New Jersey coastal plain
Fossil dinoflagellate tests have been considered to represent encysted, nonmotile stages. The discovery of flagellar porelike structures and probable trichocyst pores in the Upper Cretaceous genus Dinogymnium suggests that motile stage tests are also preserved as acid-resistant, organic-walled microfossils.
